This species diflers from all the rest of the genus in having a 

 double series of oblique discoidal cells, and in the veins being 

 very pale and dotted with black ; the antennae are also extremely 

 slender and filiform ; the general colour is luteous buff. The 

 head is very convex on the crown, with a slender black central 

 line ; on each of the lower parts of the face, near the clypeus, is a 

 small rather deep impression. The labrum is broadly cordate and 

 flat. The tips of the mandibles and the last joint of the palpi are 

 black. The antennae are about three times the length of the head,
